ELECTRICAL GUN.

Specification of Letters Patent.

Application filed May 29, 1917. Serial No. 171,697.

To all whom it may concern;

Be it known that we, LEVI; M; Bowman, (2) WILLIAM A. SMITH, citizens of the imited States, residing at Tulsa, 1n the once been sighted. the nullin of the tri 'er U C C23 to fire the gun will not pull the gun oil from the object sighted at.-

Another object of the invention is to provide an electrical gunstructure including a primer or firing cap, which carries a spark;

.ing point, so that the shell is discharged by theiormation of spark in the primer,

thereby eliminating the liability of accidental discharge of a shell, by a blow-or jolt. g 7

With the foregoing and other objects in.

- View, this invention consists in such novel features of construction, combination. and

arrangement of parts as will be hereinafter,

more fully described, illustrated in. the ac companying drawings and claimed.

In describing the invention in detail, reference will bevhad to the accompanying drawings wherein like characters designate like and correspording parts throughout the sereral'views, and in which I Figure 1 is a longitudinal section through the improved gun; 1

Fig. 2 is an enlargedtragmentary section through the gun; and i 1 Fig. 3 is a detailed section through the primer.

Referring more particularly to the'drawings, l-designates the gun barrel, and 2 the gun. stock.

gun stock in the usual manner of the COI1I1C' The barrel 1 is connected to the tion or" shot gun barrels to the stocks so that the barrel may be swung, by the actuation of the lever for placing an unexploded shell within the breech of the barrel 1.

-The stock 2 of the gun has a battery 5 mounted therein which is connected to an induction coil or transformer 6, by a wire I pivotally mounted as shown at to jump from the protruding en connected by a wire 8, to one end of an adjustable contact member 9 as clearly shown at 10 in of the drawings. The

adjustable contact member 9 is carried by a gun is pivotally mounted on apin 17 so that when the trigger is moved rearwardly the contact 13 will be forced into engagement, with the contact 12 for'closing an electricalcircuit, to discharge a shell, indicated at 18,

as will be hereinafter more'fully described.

The trigger 16 has a spring '19 connected thereto which is. also connected to a piv-- otally mountedfinger 20. The finger 20 is guided, in its pivotal movement by a guide coil 6 is grounded through a wire 20, as shown at 21, so that when the contact 13 is moved into engagcment'with the contact 12, the circuit will pass through the battery 5, wire 7, induction coil 6, upwardly through the trigger 16, pin 14, contacts12 and 13,

through. the contact member 9 and wire 8 back to the battery 5. a r The shell 18 has a primer 25 mounted therein, as is usual in shot gun shell con-' struction, which primer is composed. of an outer shell 26 .in which is mounted a plug Patented Seph, 1917.: I

trigger 16 of the gun. The trigger 16 of the I 21 and it is v The primary circuit of the induction 2?. The plug 27 is constructed of insulating t'ial and an electrode 28 extends centrail tnerethrough, and pro ects a short (l1S* ing end of the electrode 28 engage the charge 30 ot' the shell 18. The secondary coil of the transformer or induction coil 6 passes through wires 31 breech of the gun barrel. The wirev 32 engages the central electrode 28, while the wire 32 engages the shell or casing 26 of the and 32, which areheavily insulated as indicated at 33, to the tance out of theinner end of the plug 27 as i primefi so that when the-primary circuit is closed by the operation of the trigger 16, the

secondary current will flow through the Wires 31 and 32 into the electrode 28 and the casing 26, of the primer caus' a spark of the electrode 28 to the inwardly curved end 29 of the shell 26 of the primer which will explode the powder charge30 of the shelllS.

' A safety switch indicated at 31 is interposed in'the wire 8 so that when it is desired this switch may be opened for preventing accidental discharge of the gun.

A. second safety arrangement is provided, which may be quickly and easily operated by thegunner, when it is desired to: dis-' charge the gun. The second safety arrangement comprises a trigger 35 which is pivotally mountedas shown at 36 within the trigger guard 37, and directly in front of the trigger 16. A bar 38 is connected to the trigger 35 and it has an insulating plug 39 pivotally connected thereto as shown at 40 and extending upwardly therefrom. The

insulating block 39 is forced, by the action of the trigger 35 upwardly between the contacts 12 and 13 so as to prevent engagement between these members upon the operation of the trigger 16, thereby eliminating the accidentaldischarge of the gun when the switch 3-1 is closed. When the switch 34: is closed, and also the safety plug 39 is positioned between the contacts 12 and'13, and

the operator desires to dischargefthe gun, ,all that is necessary is to first operate, the

trigger 35 for moving the insulating plug 39 downwardly from between the contacts 12,

and 13, so that upon operation of-the trigger 16 the contact 13 will be moved into engagement with the contact 12, for closing the circuit and discharging the gun as previously described.

A branch wire 44 is connected to the wire 8, and toa wire 15, through a switch .46.

The wire t5 extends along the gun structure, at any convenient location, tothe muzzle of the barrel, at which point it is connected to a light socket t'i'which carries an ordinary incandescent light 18. The circuit is formed through the light 48, through the wire 4% and the gun barrel, with which the wire 20 is grounded, so that when it is desired to light the light 458, all that is necessary is to close the switch structure 16. This light may be utilized for shining the eyes of various animals, such as coons, opossums, or the like, whenhunting with the gun at night,
